Cocoknits says "I often travel with my knitting, which really takes a toll on the carefully wound cakes of yarn, as I find them unwound and tangled in my knitting bag. In an effort to keep things neat, I used to use a plastic Zip-loc bag – and eventually realized I needed a better and more eco-friendly solution. I designed a container that opens wide to accommodate a large wound skein (or two smaller ones), and then added snaps that allow you to customize the size and configuration. The bags are made out of woven, washable paper fabric which is both sturdy, yet lightweight."
We say "perfection"
